Rex, played by Ben O'Toole, is a veteran living in Boise, Idaho, who finds himself in an unexpected and harrowing situation during a visit to a local bank. He is smitten with a bank teller named Maddy, portrayed by Ashlee Lollback, and goes out of his way to manipulate the queue so he can flirt with her. Just as Rex aims to ask Maddy out on a date, chaos erupts when a group of armed robbers storm into the bank, demanding money and personal belongings from everyone present. In a moment of instincts kicking in, Rex instructs Maddy to flee to safety while he prepares to hand over his wallet. However, as chance would have it, a firearm falls out of another patron's opened purse, sparking a fierce internal debate in Rex about whether to utilize it against the armed intruders.
Through a series of flashbacks, we see Rex transforming from a lovesick admirer to a decisive figure as he engages with the robbers, managing to fight them off one by one. Unfortunately, the altercation leads to the tragic death of an innocent bystander, stirring up a controversial debate regarding Rex's actions—some view him as a hero while others label him a vigilante responsible for unnecessary bloodshed. As the narrative unfolds, Rex faces the consequences of his actions in court, where he struggles with a critical decision that will shape his future—either accepting a plea deal that guarantees 8 years in prison or risking a 20-to-life sentence should he contest the charges. Ultimately, Rex opts for the plea deal, marking the beginning of an 8-year prison term filled with reflection and torment.
Upon his release, Rex is greeted by a media circus, eager to cover his story, as he attempts to navigate his newfound (and undesired) fame. From mundane activities like grocery shopping to indulging in a burger, he is constantly bombarded by reporters and curious onlookers. In a light yet ironic twist, Rex shares his intention to escape to Finland, a decision made by whimsically shooting a spitwad at a map in his cell. As he arrives in Finland, the journey turns bizarre when he is recognized and harassed by fans, with one patron comparing him to Batman. Tension rises as he overhears an elderly couple discussing something suspicious about him, and at the airport, he discovers the alarming coincidence that the airport codes for Boise to Helsinki translate as "Boy to Hell."
After boarding a taxi to his destination, Rex is overcome by sleep gas and awakens chained in a grim basement—a makeshift torture chamber belonging to a cannibalistic family. There, he confronts a loss of agency as he is rendered helpless, suspended with one leg amputated. His only companion in this horrific place is a personified vision of his conscience, which guides him through this nightmare. They quickly deduce that Rex is being, quite bizarrely, held captive by a family that seems to be taking pleasure in torturing him.
Amid the turmoil, a young boy named Olaf discovers Rex in this nightmarish state. Rex seizes the opportunity to negotiate his freedom by holding Olaf hostage, but the situation complicates when Olaf's older sister, Alia, intervenes. Alia, portrayed by Meg Fraser, reveals the disturbing realities of her family's history and their deeply ingrained violent tendencies, explaining how they have fed on American travelers to satisfy her brother Pati's grotesque cravings. Despite her fear of her family, Alia feels a connection to Rex, stemming from their shared traumatic experiences. She offers him a means to aid in his escape but struggles with loyalty to her sinister family.
As the plot thickens, the family's arrival from the hospital escalates the tension. Despite Rex’s efforts, he is incapacitated again, leading to more chaotic flashbacks that reveal his earlier actions during the bank robbery. The cinematic palette encapsulates the juxtaposition of his past as a reluctant hero and his current status as a prey. Throughout it all, he grapples with haunting memories of his decisions and the fallout from that fateful day.
When Rex regains consciousness and confronts Uncle Arto, who intends to finish amputating his remaining leg, he finds the will to fight back. Using the knife given to him by Alia, he kills Uncle Arto and begins his quest for survival, fashioning weapons from the odds and ends within the basement. He stealthily prepares to battle the remaining family members, joining forces with Alia, who has noted the chaotic behavior of her family and offers her unexpected assistance. The stakes climb higher as Rex faces Pati, a daunting giant fueled by familial rage, and overcomes him with sheer determination.
In an exhilarating climax, Rex and Alia escape together, reflecting on their harrowing experiences and the bond that has formed between them. They are later depicted back in the States, seemingly navigating a new life together, their traumatic past behind them. Yet, a darker hint emerges as Alia's psychopathic tendencies surface, leading to an unsettling moment at a party where her jealousy turns lethal. Simultaneously, Olaf, who is oblivious to Alia's potential menace, holds onto the remnants of his old family and envisions a future filled with American banquets.
This gripping narrative explores themes of redemption, trauma, and the horrifying dimensions of human nature, leaving viewers questioning the line between hero and villain in moments of crisis.
